UNITED STATES MAX SHERMAN, OF LOS ANGELES, CALIFORNIA.

PORTABLE SHAPER.

Application filed April 21, 1924. Serial No. 707,897.

I '0 all whom it may concern:

Be it known that 1, MAX SHERMAN, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented certain new and useful Improvements inPortable Shapers, of which the following is a specification.

My invention relates generally to wood working machinery and moreparticularly to a-shaper for producing light moldings, the principalobjects of my invention being to produce a shaping or molding machinethat is of relatively simple, strong and durable structure, and which iscomparatively small and light in weight, thereby permitting the machineto be readily carried or shifted from one point to another; to provide amachine of the. character referred to that may be very economicallyoperated from the standpoint of power consumption; to construct themachine so that it may be readily attached to any substantial support,such as a larger machine, a work table, bench or the like and, further,to provide a relatively adjustable structure having comparatively. fewparts that can be advantageously used in the production of light woodenmoldings.

With the foregoing andother objects in view, my invention consists incertain novel features of construction and arrangement of parts thatwill be hereinafter more fully described and claimed and illustrated inthe accompanying drawings in which- Fig. 1 is a front elevational viewof my improved molding machine.

Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1.

Figs. 3 and 4: are perspective views of different forms of work supportsthat are used in connection with my improved machine.

Fig. 5 is a perspective view of a pin that is used as a work guide andas a shaft locking member.

Fig. 6 is a top plan view of the machine.

Fig. 7 is a horizontal section taken on the line 77 of Fig. 1.

Fig. 8 is a horizontal section taken on the line 88 of Fig. 1.

Fig. 9 is a horizontal section taken on the line 99 of Fig. 1.

Referring by numeralsto the accompanying drawings, 10 designates a baseplate of any suitable size andshape and which is adapted to be rigidlysecured to a suitable support by means of bolts or clamps, and formedintegral with the forward end of said basevplate is a standard 11, inwhich is formed a centrally arranged opening 12. Suitable braces 13 arearranged between the side portions of base 10 and standard 11. Securedto the upper portion of standard 11 is a horizontally disposed forwardlyprojecting bracket 14 and detachably secured on the top thereof and tothe top of the standard is a fiat work supporting table 15 in thecente'rof which is formed, an opening 16. i

Secured on top the front faceof standard 11 and adjacent to theside-edges thereof are vertically disposed parallel rails 17 havingundercut or bevelledinner edges 18.

Arranged for sliding movement between.

the rails 17 is apair of bearing blocks or boxes 19 that are spacedapart and the ends of said blocks are .provided with bevelled faces 20that engage beneath the bevelled faces 18 on rails 17. i

These bearing blocks may be of any desired construction and to minimizefriction they may be provided with suitable ball or roller bearings. V

J ournalled in the bearing blocks 19 is a vertically disposed shaft 21,the upper portion of whichprojects through opening 16 and 'said upperportion being provided with a shoulder 22.

Adapted to rest on shoulder 22 is a collar 23, the upper face of whichis grooved as designated by 24:, in order to receive the lower edges ofa pair of mold cutting knives such as 25.

Arranged on top of these knives is a sec- 1 0nd collar 26, grooved inits under face to receive the upper edge of the knives and, to clamp theknives between the collars, and the lower collar 22, a nut 27 is screwseated on the threaded upper end 28 of the shaft.

In order to cut grooves or channels in molding strips or the like, asmall saw or cutting disc such as 29 may be detachably mounted on theupper end of shaft 21.

Shaft 21 and its bearings 19 are adapted to be adjusted vertically toposition the cutting blades 25 in different planes above the table 15,by a screw 30 that is seated in the forward end of base 10, the lowerend of said screw having a hand wheel 31 and the upper end beingrotatably connected to lower bear ing block 19.

Means for locking screw and associated parts in their adjusted positionscomprises a lock nut 32 that is seated on said screw below base 10 andsaid lock nut being provided with a handle 33. v

Shaft 21 maybe driven in any suitable manner, preferably by'means ofabelt 34 that passes through opening 12- and engages said 'sha-ftbetween the bearings 19.

- Toform 'abearing against whichthework is placed when first moved intoengagement with the cutting head, a pin such as 35 is detachably seatedin an aperture 36 in table 15. v

This pin may also be inserted in an aperture- 37 in-the lower portion ofshaft '21 and bearagainst-standard 11 to hold'the shaft againstrotationwhen a wrench isapplied to nut 27 for thepurpose of-tightening orunscrewing same.

To provide a convenient support for cur've'dpiecesthat are cut intomoldings on my improved machine, table 15 maybe re- 7 moved and-a convextable of the form illustrated inFig. 3 or a concavetable asillustratedin Fig. 4 may be secured on bracket 14: and standard 11.

In the use of my improved'shaper or moldingmaehine, the proper cuttingblades are clamped between collars 2 land 26 and screw 30 isthenmanipulatedto moveshaft 21 1 and carried parts vertically *so as to I10- cate the rotary cutting head the proper distance above table 15.

work positioned on table 15, is manipulated so as to be engaged by thecutting edges of blades 25.

A shaperor molding machineof-my improved construction is comparativelysimple, may be readily shifted from one position to another, and as themachine requires little power in its operation, it can be advantageouslyand economically employed in the production of all-forms of lightmoldings.

It will be understood that minor changes in the size, form andconstruction ofthe various partsof my improved portable shaper may bemade andsubstituted for those herein described without departing fromthe spirit of the invention, the scope of which is set forth in theappended claim.

I claim as my invention:

In a portable shaper, an upright frame, parallel rails arrangedvertically on the front face of said frame,.a-horizontally 'disposedU-sh-a-pedframesecuredto the front face of the upright framie attheupper-end thereof, a table'arranged on top of the horizontallydisposed-U-shaped frame and provided at its center with an opening,bearings arranged to slide on'the upright frame between the parallelrailsthereon, the space between the horizontally disposed U-shapedframeand tl ie'upright-fr-ame being of sulficientsize to accom-modatethe upper one of the sliding bearings, a *shaft -journalled in thebearings, cutter-clampi1rgmeans on the upper end of said shaft, whichclamping means includes a'pair'of discs, the lower one of the latterbeing adapted 1 to 'move freely through the openingin the table when theshaft is adjusted vertically and an adjusting screw seated in the lowerfront portionof theupright frame, and 'swivelled to the lower one oftheslidilrg bearings.

In testimony whereof-I aflix my signature.

' SHERMAN.
